c1428b3f45 mac80211: fix allmulti/promisc behaviour
When an interface with promisc/allmulti bit is taken down,
the mac80211 state can become confused. This fixes it by
making mac80211 keep track of all *active* interfaces that
have the promisc/allmulti bit set in the sdata, we sync
the interface bit into sdata at set_multicast_list() time
so this works.

b52f2198ac mac80211: fix ieee80211_set_multicast_list
I recently experienced unexplainable behaviour with the b43
driver when I had broken firmware uploaded. The cause may have
been that promisc mode was not correctly enabled or disabled
and this bug may have been the cause.

Note how the values are compared later in the function so
just doing the & will result in the wrong thing being
compared and the test being false almost always.

1f305323ff [NETFILTER]: Fix kernel panic with REDIRECT target.
When connection tracking entry (nf_conn) is about to copy itself it can
have some of its extension users (like nat) as being already freed and
thus not required to be copied.

Actually looking at this function I suspect it was copied from
nf_nat_setup_info() and thus bug was introduced.

Report and testing from David <david@unsolicited.net>.

[ Patrick McHardy states:

	I now understand whats happening:

	- new connection is allocated without helper
	- connection is REDIRECTed to localhost
	- nf_nat_setup_info adds NAT extension, but doesn't initialize it yet
	- nf_conntrack_alter_reply performs a helper lookup based on the
	   new tuple, finds the SIP helper and allocates a helper extension,
	   causing reallocation because of too little space
	- nf_nat_move_storage is called with the uninitialized nat extension

	So your fix is entirely correct, thanks a lot :)  ]

0a06ea8718 [WIRELESS] WEXT: Fix userspace corruption on 64-bit.
On 64-bit systems sizeof(struct ifreq) is 8 bytes larger than
sizeof(struct iwreq).

For GET calls, the wireless extension code copies back into userspace
using sizeof(struct ifreq) but userspace and elsewhere only allocates
a "struct iwreq".  Thus, this copy writes past the end of the iwreq
object and corrupts whatever sits after it in memory.

Fix the copy_to_user() length.

This particularly hurts the compat case because the wireless compat
code uses compat_alloc_userspace() and right after this allocated
buffer is the current bottom of the user stack, and that's what gets
overwritten by the copy_to_user() call.

5487796f0c [TCP]: Problem bug with sysctl_tcp_congestion_control function
From: "Sam Jansen" <sjansen@google.com>

sysctl_tcp_congestion_control seems to have a bug that prevents it
from actually calling the tcp_set_default_congestion_control
function. This is not so apparent because it does not return an error
and generally the /proc interface is used to configure the default TCP
congestion control algorithm.  This is present in 2.6.18 onwards and
probably earlier, though I have not inspected 2.6.15--2.6.17.

sysctl_tcp_congestion_control calls sysctl_string and expects a successful
return code of 0. In such a case it actually sets the congestion control
algorithm with tcp_set_default_congestion_control. Otherwise, it returns the
value returned by sysctl_string. This was correct in 2.6.14, as sysctl_string
returned 0 on success. However, sysctl_string was updated to return 1 on
success around about 2.6.15 and sysctl_tcp_congestion_control was not updated.
Even though sysctl_tcp_congestion_control returns 1, do_sysctl_strategy
converts this return code to '0', so the caller never notices the error.

proper strategy handler, but syscall sysctl is deprecated.

There are other sysctl definitions that are commented out or work with 
the default sysctl_data strategy. I did not touch these.

dab6ba3688 [INET]: Fix potential kfree on vmalloc-ed area of request_sock_queue
The request_sock_queue's listen_opt is either vmalloc-ed or
kmalloc-ed depending on the number of table entries. Thus it 
is expected to be handled properly on free, which is done in 
the reqsk_queue_destroy().

However the error path in inet_csk_listen_start() calls 
the lite version of reqsk_queue_destroy, called 
__reqsk_queue_destroy, which calls the kfree unconditionally. 

Fix this and move the __reqsk_queue_destroy into a .c file as 
it looks too big to be inline.

As David also noticed, this is an error recovery path only,
so no locking is required and the lopt is known to be not NULL.

reqsk_queue_yank_listen_sk is also now only used in
net/core/request_sock.c so we should move it there too.

d90bf5a976 [NET]: rt_check_expire() can take a long time, add a cond_resched()
On commit 39c90ece75:

	[IPV4]: Convert rt_check_expire() from softirq processing to workqueue.

we converted rt_check_expire() from softirq to workqueue, allowing the
function to perform all work it was supposed to do.

When the IP route cache is big, rt_check_expire() can take a long time
to run.  (default settings : 20% of the hash table is scanned at each
invocation)

Adding cond_resched() helps giving cpu to higher priority tasks if
necessary.

Using a "if (need_resched())" test before calling "cond_resched();" is
necessary to avoid spending too much time doing the resched check.
(My tests gave a time reduction from 88 ms to 25 ms per
rt_check_expire() run on my i686 test machine)

c67625a1ec [NET]: Remove notifier block from chain when register_netdevice_notifier fails
Commit fcc5a03ac4:

	[NET]: Allow netdev REGISTER/CHANGENAME events to fail

makes the register_netdevice_notifier() handle the error from the
NETDEV_REGISTER event, sent to the registering block.

The bad news is that in this case the notifier block is 
not removed from the list, but the error is returned to the 
caller. In case the caller is in module init function and 
handles this error this can abort the module loading. The
notifier block will be then removed from the kernel, but 
will be left in the list. Oops :(

I think that the notifier block should be removed from the
chain in case of error, regardless whether this error is 
handled by the caller or not. In the worst case (the error 
is _not_ handled) module will not receive the events any 
longer.

is based on. If conventional recovery path is chosen, this won't
be significant at all. In practice, any small enough value will

FRTO's formula is now equal to what tcp_enter_cwr() uses.

5f1a485d59 [PKT_SCHED]: Check subqueue status before calling hard_start_xmit
The only qdiscs that check subqueue state before dequeue'ing are PRIO
and RR.  The other qdiscs, including the default pfifo_fast qdisc,
will allow traffic bound for subqueue 0 through to hard_start_xmit.
The check for netif_queue_stopped() is done above in pkt_sched.h, so
it is unnecessary for qdisc_restart().  However, if the underlying
driver is multiqueue capable, and only sets queue states on subqueues,
this will allow packets to enter the driver when it's currently unable
to process packets, resulting in expensive requeues and driver
entries.  This patch re-adds the check for the subqueue status before
calling hard_start_xmit, so we can try and avoid the driver entry when
the queues are stopped.

4ce5ba6aec [NETFILTER]: Consolidate nf_sockopt and compat_nf_sockopt
Both lookup the nf_sockopt_ops object to call the get/set callbacks
from, but they perform it in a completely similar way.

Introduce the helper for finding the ops.

d71209ded2 [INET]: Use list_head-s in inetpeer.c
The inetpeer.c tracks the LRU list of inet_perr-s, but makes
it by hands. Use the list_head-s for this.

91cf45f02a [NET]: Add the helper kernel_sock_shutdown()
...and fix a couple of bugs in the NBD, CIFS and OCFS2 socket handlers.

Looking at the sock->op->shutdown() handlers, it looks as if all of them
take a SHUT_RD/SHUT_WR/SHUT_RDWR argument instead of the
RCV_SHUTDOWN/SEND_SHUTDOWN arguments.
Add a helper, and then define the SHUT_* enum to ensure that kernel users
of shutdown() don't get confused.
